Hydrocynus tanzaniae, the blue tigerfish, is a large African predatory freshwater fish.
The eastward flowing rivers of Tanzania and in the Ruaha and Rufiji river systems. [2]
Hydrocynus tanzaniae is a large, predatory fish. It has pronounced dentition similar to those found in Hydrocynus forskahlii . [2] The holotype was nine and a half inches long (247mm), [2] but specimens have been caught by fishermen greater than 27 inches (70 cm) and 25 pounds (11 kg). [3] At a given length, H. tanzaniae has a deeper body than either H. forskahlii or H. vittatus . [4] These fish are a silvery grey color [3] and often have pronounced stripes. [2] [3] They often have markings in blue, black, pink, green and red, [3] making them among the more colorful of African tiger fish. Uniquely among the African tiger fish, they have a blue adipose fin [3] (other species have a black adipose fin).
Characiformes is an order of ray-finned fish, comprising the characins and their allies. Grouped in 18 recognized families, more than 2000 different species are described, including the well-known piranha and tetras.
The cardinal tetra is a freshwater fish of the family Characidae of order Characiformes. It is native to the upper Orinoco and Negro Rivers in South America. Growing to about 3 cm (1.2 in) total length, the cardinal tetra has the striking iridescent blue line characteristic of the genus Paracheirodon laterally bisecting the fish, with the body below this line being vivid red in color, hence the name "cardinal tetra". The cardinal tetra's appearance is similar to that of the closely related neon tetra, with which it is often confused; the neon's red coloration extends only about halfway to the nose, and the neon's blue stripe is a less vibrant blue.
The brown bullhead is a fish of the family Ictaluridae that is widely distributed in North America. It is a species of bullhead catfish and is similar to the black bullhead and yellow bullhead. It was originally described as Pimelodus nebulosus by Charles Alexandre Lesueur in 1819, and is also referred to as Ictalurus nebulosus.
The Congo tetra is a species of fish in the African tetra family, found in the central Congo River Basin in Africa. It is commonly kept in aquaria.
Tigerfish can refer to fish from various families, and derives from official and colloquial associations of these with the tiger. However, the primary species designated by the name "tigerfish" are African and belong to the family Alestidae.
The gafftopsail catfish is found in the waters of the western central Atlantic Ocean, as well as the Gulf of Mexico and the Caribbean Sea. It has long poisonous spines which can cause painful wounds. It feeds on crustaceans and other fish. The male of the species fertilizes the eggs of the female, and broods them in his mouth until they hatch. The gafftopsail feeds throughout the water column. This fish is a common catch in the Southeastern US, although it may be found as far north as New York. They are considered strong fighters by anglers. They are taken from piers, jetties, reefs, and the surf, as well as bottom fishing or flats fishing. They are caught with hard lures as well as soft plastics, cut bait, and live or dead shrimp. Some fishermen use traps for catfish, a method regulated by some states.
The silver redhorse is a species of freshwater fish endemic to Canada and the United States. Sometimes called redhorse or sucker for short, it is in the family Catostomidae with other suckers. The species is distributed from Quebec to Alberta and is also in the Mississippi River, St. Lawrence River, Ohio River, and the Great Lakes basins. The current world record is 14 pounds, 14 ounces, caught by Chris Stephenson on Pickwick Lake in Alabama, April 1995 and certified by National Freshwater Fishing Hall of Fame.
Hepsetus odoe, the African pike characin, is a predatory freshwater characin belonging to the family Hepsetidae. It was formerly considered that there was a single species of Hepsetus pike characin but recent studies have led to the species being split and Hepsetus odoesensu stricto is the west African representative of the group.
Tor khudree, the Deccan mahseer, Khudree mahseer, or black mahseer, is a freshwater fish of the carp family found in major rivers and reservoirs of India and Sri Lanka. Found throughout India, following large-scale introductions of artificially-bred fish across the country, but found of the largest size and in the greatest abundance in mountain or rocky streams.
The fish as originally described by Sykes in his November 1838 paper 'On the Fishes of the Dukhun' as Barbus khudree, is a silvery-bluish coloured fish, with blood red fins or fins tipped with a bluish tinge. The type locality is the Mula-Mutha River close to the Indian city of Pune, a part of the Krishna River basin.
Although there have been efforts to artificially breed this mahseer since the early1970's, there is no way to determine if these fish are Tor khudree, as the populations within the type locality have gone extinct.
Hydrocynus is a genus of large characin fish in the family Alestidae commonly called "tigerfish," native to the African continent. The genus name is derived from Ancient Greek ὕδωρ ("water") + κύων ("dog"). The genus contains five species, all popularly known as "African tigerfish" for their fierce predatory behaviour and other characteristics that make them excellent game fish. Hydrocynus are normally piscivorous, but H. vittatus is the only freshwater fish proven to prey on birds in flight.
The Siamese tigerfish, also known as the Siamese tiger perch, is a critically endangered Asian fish native to the Chao Phraya, Mae Klong and Mekong basins. It has vertical yellow and black stripes running the length of its body. The dorsal fin has a spiny appearance. Siamese tigerfish grow to 40 cm (16 in) in standard length.
Hydrocynus goliath, also known as the goliath tigerfish, giant tigerfish, or mbenga, is a very large African predatory freshwater fish of the family Alestidae.
Hydrocynus vittatus, the African tigerfish, tiervis or ngwesh is a predatory freshwater fish distributed throughout much of Africa. This fish is generally a piscivore but it has been observed leaping out of the water and catching barn swallows in flight.
Saltwater fish, also called marine fish, are fish that live in ocean water. Saltwater fish can swim and live alone or in a large group called a school.
Hydrocynus brevis, also known as the tigerfish, Nile tigerfish or Sahelian tigerfish, is a predatory freshwater fish distributed throughout Africa.
There are two major sources of fish in Uganda; one is from aquaculture, the other from fishing in rivers and lakes. Different types of fish flourish in different water sources. The waters of Uganda contain an impressive array of fish species—over 90 in all. This count does not include the Haplochromis complex, which itself is made up of more than 200 species. Fish that are the target of most commercial and subsistence exploitation include species of Lates, Oreochromis, the herring-like Alestes, the catfishes Bagrus and Clarias, Hydrocynus, the small pelagic “sardine” Rastrineobola, Protopterus (lungfish), and the haplochromines.
Hepsetus cuvieri, sometimes known as the African pike or Kafue pike characin, is a predatory freshwater fish found in southern Africa. This species was described in 1861 by the French naturalist Francis de Laporte de Castelnau.
Hydrocynus forskahlii, the elongate tigerfish, is a species of predatory characin from the family Alestidae which is found in northern and western Africa.
